HTML was originally designed just to mark the content or structure of a web page but shortly after its inception this was broken and various tags to control formatting were invented. However, this mixing of HTML and styles can lead to difficulties in maintaining and updating your site, especially with regard to internationalisation, accessibility and more modern technologies such as XML. Cascading Style Sheets (CSS) was the technology invented to specify the styles for web pages so that HTML could go back to specifying the content of the pages. CSS + HTML give us separation of design from content and makes maintaining and updating web pages far easier.

This course covers all of the essentials of the updates in HTML4 and includes the conventions and rules behind XHTML, how to make your pages more accessible using syntactically correct XHTML, where to use and store CSS styles, how to apply styles, what styles you can apply – and highlights any browser differences along the way. The course will also cover CSS positioning, which at first can seem quite confusing so we give examples and hints to explain the subtleties.
